Hi, Lorenzo! Thank you for your reply.
Now as we try to implement our algorithm to the real wireless devices, we would like to purchase some Atheros WLAN adapters, whose specification requirements are as follows. - Adapters for laptop or netbooks with Linux. - Runs with Linux ath9k (or ath5k) driver. - Support of per-packet TPC, which users can manipulate via driver or Linux code. can . We are afraid that some adapters might support TPC physically but blocks users from playing with it. - Form factor: USB will be best. If not, CARDBUS/PCMCIA is our second choice. If you have a good adapter that fulfills the requirements, could you please let us know?
